if the bios chip is damaged he have to download the bios file to a floppy and try and force a reflash of the newest bios file. if the mb wont flash due to a bad chip. see if the bios chip for his mb is soilder on or is a push pin cmos chip. if it the latter then for 10.00 the chip may be on ebay to buy and he can replace it and reflash the bios. if not it time for a new pc.
